You see Mogwai? I told you to ask Kev how he did his.

BRILL job Kev. Now how do I get Blue to make me a -8AN line kit for my six pack?

You're on your own with that one Dave! made one once for the six pack tunnel ram I had in the Dart, never again, I don't think I've ever done anything quite so fiddly and frustrating, you need some serious patience working between those carbs.....

Had a feeling you were going to say something along those lines Blue.

Just out of interest, and in case I feel like giving it a go myself, what sizes are the fittings used on those carb hard lines and the fittings on the fuel bowls? Just so I would know what to ask for. I find the brass fittings on the standard six pack lines get a bit chewy after a while and they are expensive to replace.

Any reason not to use flexable braided hose between the carbs or would the tight bends reduce the diameter do you think?

Did mine with -6 (3/8") Dave, not enough room for -8. You could use flexible line if there was enough room to get the hose ends in there, I used hard line so I could get the necessary tight bends. The other big problem is the size of the tube nuts, huge compared to the six pack ones, much fun getting a spanner onto those. These are the Speedflow part numbers I used,

3xCarb adaptors 700-6
6xTube nut 818-6
6xTube sleeve 819-6
3/8" Aluminium tube, buy far too much to allow for errors!
3x JIC to 1/4"NPT adaptors 816-06

This will get you from the carbs to a fuel log which I thought was the easiest way to plumb it.

Gotta big up Blue for helping big-time on this project. (Especially the carb plumbing

). I now know me /8 from /6, NPTs etc. etc. Would have been lost without him. Thanks also to Johnny Mental at BJ Nostalgia for use of the folding machine. Special thanks to Visa for funding the AN habit!

Thanks for that Blue. I will have to measure it but I think the standard fuel lines on a six pack are smaller than 3/8"? If so this would be an improvement.
Yeah I was thinking of keeping it simple by making a fuel log. I have -8AN from the mechanical pump to the filter and then to the regulator. I would like to run -8AN to a fuel log and then -6AN to each carb from there would be fine.

The other thing I would like to do is run -8AN from the tank to the fuel pump. The existing fuel sender and line is 3/8" to the pump but there are a few tight bends where the diameter is reduced a bit.

Any thoughts on how to plumb a stock tank with AN fittings without doing any welding and blowing our new tank and myself up? I take it those on the plastic tank work with nut/washers?

On a stock tank the lowest part of the tank is at the front but of course under power the fuel runs to the back so what to do????

DrogoBand put 1/2" line into his stock tank, just drilled the sender unit plate and bolted a bulkhead fitting in with 1/2" hard line replacing the old pick up, if I remember rightly. Then put a filter in near the tank. Why do you have the filter after the pump? Would it be better filtering before the pump? I know they came from the factory after the pump but basic engineering common sense says it should be before. Or am I missing something?

The way I have things laid out it would be tricky to have the filter before the pump. It is MASSIVE! A big Chrome Summit job. I have mounted it in front of the radiator to keep it cool and because these filters are only rated at 95gph (but at what pressure I know not) I thought it wise to let it see full pressure from the pump (mechanical pumps are better at pushing than pulling) and regulate it after the filter.

Yea, Kev's basically correct, we didn't want to be welding on the tank either! What we did on Dave's charger was to open up the stock sender to accept a -8 bulkhead fitting that seals with nylon washers, and then fit a long ally tube towards the rear of the tank. How far back you can extend it depends on tank shape, with a flat bottomed tank you can go right to the rear, if it has a slope to it then you can only go that far. Racing with a full tank of gas should stop the pickup from drawing air. With a little patience you can detatch the sender assembly from the original pickup and cable tie it to the new ally tube so that it still works. I think Dave had a photo of the modified unit. Once you have that male -8 connexion on the sender plumbing to the front of the car is pretty simple. If you do it you might want to price it up for running braided hose from the sender right the way forward to the front as that way you only need 2 hose ends which is easier and sometimes cheaper than a combination of braided and hard line and all the fittings that that involves. Yes, the original six pack lines are smaller than 3/8.

Mmm.

It would be a pity to cut up a NOS 3/8" (not reproduction) sender. And I have had trouble in the past making my own and trying to get the fuel level thing to work.

I was thinking it might be better to leave the sender alone (just block it off) and put a male fitting into the bottom of the tank. The problem being of course how do you get in with a hand or tool to put a nut and nylon washer on the inside. Actually I think I could do that to get it started with a bit of a fiddle but how to get it to tighten?

I will think some more on that one.

For Kev here is a reminder of where my fuel filter ended up!

What's this 'log' of which you speak? My imagination decided it's some sort of carb version of a fuel rail that would feed injectors? Or am i

way off?
Dave- is it not a bit risky having fuel so near the front of your car :violent3:

?

Cue smug grin

thanks Dave!!!

Time to re-awaken this ole thread

I'm gonna sink my fuel cell into the trunk floor similar to yours Kev.
Any tips?
Some of the old pics aren't coming up on my pc, where did you run the 1" supports?
What did you make the straps out of?
How deep did you sink it into the trunk?

I'd like to mount my pump/filter etc in the trunk, prob alongside the cell. Any reasons against this?
